V

A furtherbracket 22 on the machine frame 10 supports a transverse rod 23 having fixed thereto the plate 24 ata desired angular position. Mounted on this plate 24 opposite the projections 19 of the plate 19 are respective brackets 25 for justifying rollers 26 which are preferably formed of light material such as aluminum, and being narrow in width of face and adapted by their position and arrangement to relatively fit into the slots 27 in the extensions 19 (Figs. 2 and 3). Each of these rollers 26 has theaxle 28 passed therethrough, the ends of the axle being received in a respective notch 29 formed in the lower part of the bracket 25, this notch being closed by a plate 30. The lower end of each of the brackets 25 is bifurcated and the inwardly directed surfaces of the two tines fit closely to the endsof the respective rollers 26 so that the roller is substantially pre vented from rocking, but is permitted to move up and down by the play of its axle 28 in the notches 29. A slot 31 is formed at the upper end of the respective brackets 27, so that the respective bracket may be adjusted and locked by therespective cap screws 32 passing through. this slot and into the plate 24.

In operation, as a blank S is brought forward by the conveyor'tapes 12 and 14 which continue to 'moveat a proper speed, being equivalent to the peripheral speed of the printing drum 11, the front edge of the blank comes against the peripheral surfaces of the series of justifying rollers 26, which are then slots 27. The front edge of the advancing blank is therefore stopped definitely at this point, and-the entire front edge is alined or justified along a line extending parallel to the axis of the printing drum 11. In the timing of the operation ofthe various parts, it will be understood that it is customary to provide an interval of delay from the momentof expected arrival of the front edge of this blank S at this position, for this justification to occur in case some part of the blank has been detained. By reason of the independent positioning of the conveyor tapes 12 and 14, and their simultaneous driving, the justification is accurately efiected.

At the end of this alloted time interval, the.

gripping members" 20 on the printing drum 11 are caused to close upon the front edge of this blank Sh Heretofore, the tapes have continued to advance the rear portion of the gravity when the blank has passed. occupying their lowermost position in the blank, but have not acted upon or moved the front edge beyond the blocked position of 'alinement established by the reception of the counter-clockwise movement of the printing drum 11, the entire blank isdrawn forward along the plate 19 and over the projections 19 thereof, the drag exerted by the gripping of the clamping fingers 20 causing thisfront edge to be pulled beneath the justifying rollers 26 so that the latter are caused to rise up out of their respective slots 27 and travel 1 along the upper surface of the blank S. By

the journaled arrangement of the rollers substantially little friction is afforded to the blank S while so drawn, and by reason of the continuing advancement ofthe tapes 12 and 14, very-little pull is necessary to bring the 1 blank forward and upon the printing drum 11 for printing, for example, by the print- I ing roller 40 in Fig. 1. I

As soon was the rear edge of the blank S has passed, the several justifying rollers 26 drop into their slots 27 again under the influence of gravity, and by its engagement with the front and rear walls of the respective notch 27, the respective roller is eifectually prevented from spinning, so that a second blank closely following the blank which has just been fed onto theprinting drum 11, will not tend to ride under the respective justifying roller 26.

In particular, it will be noted that the justifying rollers are entirely independent one of another and have 'no mechanical connection thereto, their operation being deter mined solely by the movemento'f the blank S as effected by the gripping members 20 on the printing drum, and by the action of an illustrative form of execution, it willbe understood that it is not limited solely to such employment, but may be used in many ways within the scope of the, appended claims.

WVhat I'claim as new anddesire to secure by Letters Patent isz 1. In a mechanism to feed sheets to'a rotating drum having a sheet gripper and means to operate the same to grip a sheet at a While the invention'has been-describedin predetermined point of the rotation, a 0on5 tinuously driven feeding conveyor, a guide member to carry the sheets from the'conveyor to the drum and including a portion extendmember to retain the sheet untilit has been seized by said gripper.

2. In a mechanism to feed sheets to a rotating drum having a sheet gripper and means to operate thesame to grip a'sheet at a predetermined point of the rotation, a continuously driven feeding conveyor, a guide member to carry the sheets from the conveyor to the drum and including portions extending beyond the grippingv point of the gripper and spaced axially of the drum at either side ofthe path of the gripper, said extended portions of saidmember having slots therein alined in a direction parallel to the axis of the drum, and a justifying device entering eachslot and cooperatingvwith said member so that when the sheet moves over the guide member it is retained by said 7 justifying device until it has been seized by said gripper.

In a mechanism to feed sheets to a rotating drum having a sheet gripper and means to operate the sametogrip a sheet at a predetermine'd point of the rotation, a feeding conveyor, a guide member to carry thesheets from the conveyor to the drum and including portions extending beyond the gripping pointof the gripper and spaced axially of said drum from the path of the gripper, in-

dividual justifying means cooperating with each of said extended portions to retain the sheet until it has been seized by the gripper,

said justifying means being operated by the sheet when seized by the gripper to release the sheet for movement with the rotating 1 drum.

4;. In a mechanism for feeding sheets to a rotating drum having a sheet gripper, a consaid members.

5. In a mechanism to feed sheets to a moving member having asheet gripper, a continuously driven feedlng conveyor, a guide member .to carry the sheets from the conveyor to the drum, said member having a plurality of slots therein, and a plurality of justifying rollers normally located in said slots and sfrictionally engaging vwith the walls thereof to prevent rotation of the rollers, said rollers'and member cooperating to retain the individual sheet until it has beenseized by said gripper, said rollers, thereupon being raised by the sheetduring its forward movement and rolling over the sheet during the passage of the latter over the guide member to the drum.

6. In a mechanism to feed sheetsto a rotating drum having a sheet gripper, a continuously driven feeding conveyor, a guide membar to carry the sheets from the conveyor to the drum, said member having projecting portions extending along the periphery of the drum in spaced relationship, said grippers passing between'said portions, said portions having slots alined in a direction paral lel to the axis of the drum, independent ustifying means adapted to be moved clownward, by gravity to enter said slots from above when no sheet is located therebeneath so that a sheet fed by the conveyor is retained until it has been seizedbysaid gripper, said member being raised by said sheet when moved by said gripper whereby to permit the drawing of the sheet over the guide member by said gripper.

In a mcchanismto feed sheets to a rotating drum having a sheet gripper, a feeding conveyor, a. guide member to carry the sheets from the conveyor to the drum, said guide members having a plurality of slots, a plurality of brackets, each of said brackets having notches therein, a closing plate to enclose each of said notches, a plurality of rollers each having an axle, said axles being movable in said notches under the action of gravity, and being adapted to enter said slots to cooperate therewith to retain an individual sheet until it has been seized by said gripper, and thereby raised by said sheet against the action of gravity so that the sheet may pass therebeneath, said bracket preventing the rocking of the respective roller and axle about their axes.

In testimony whereof, I aflix my signature.
